RF 9 is a neuropeptide FF receptors antagonist.
Neuropeptide FF (NPFF) has been isolated originally from bovine brain through its cross-reaction with antibodies to the molluscan cardioexcitory peptide FMRF-NH2, which possesses the similar C-terminal sequence. Recent studies shows that NPFF belongs to a neuropeptide family including two G protein-coupled receptors (NPFF1 and NPFF2) and two precursors (pro-NPFFA and pro-NPFFB). Both in vitro and in vivo studies have indicated that NPFF involves in a variety of biological actions.
In vitro: RF9 was found as a potent and selective NPFF receptor antagonist. RF9 was shown to be able to selectively bind to recombinant NPFF1 or NPFF2 receptors expressed in CHO or COS-1 cell and could also in vitro antagonize the agonism induced by NPFF and NPVF in the functional assays [1].
In vivo: Aminal in vivo study showed RF9 (30 nmol) injection failed to induce significant effect, but RF9 could completely antagonize the hypothermia of NPFF after cerebral administration in mice. Additionally, RF9 (30 nmol) co-injected in the third ventricle reduced the hypothermia induced by morphine or nociceptin/orphanin [2].
Clinical trial:N/A

大多数药物在体内都是和特异性受体相互作用,改变细胞的生理生化功能而产生效应。目前已经确定的受体有30多种,根据受体存在的标准,受体可大致分为三类:
1.细胞膜受体:位于靶细胞膜上,如胆碱受体、肾上腺素受体、多巴胺受体、阿片受体等。
2.胞浆受体:位于靶细胞的胞浆内,如肾上腺皮质激素受体、性激素受体。
3.胞核受体:位于靶细胞的细胞核内,如甲状腺素受体。
另外也可根据受体的蛋白结构、信息转导过程、效应性质、受体位置等特点将受体分为四类:
1.含离子通道的受体(离子带受体):如N-型乙酰胆碱受体含钠离子通道。
2.G蛋白偶联受体:M-乙酰胆碱受体、肾上腺素受体等。
3.具有酪氨酸激酶活性的受体:如胰岛素受体。
4.调节基因表达的受体(核受体):如甾体激素受体、甲状腺激素受体等。
有些受体具有亚型,各种受体都有特定的分布部位核特定的功能,有些细胞也有多种受体。
请教各位大神,我最近在做WB,565KD的蛋白,动物组织的样品,听说样品制备需要蔗糖裂解液,请问这个是必须的嘛?用一般蛋白提取方法制备可以吗?还有电泳和转膜条件能否分享一下。不胜感激
